Artificial pacemaker
A pacemaker (or artificial pacemaker, so as not to be confused with the heart's natural
pacemaker) is a medical device which uses electrical impulses, delivered by
electrodes contacting the heart muscles, to regulate the beating of the
heart. The primary purpose of a pacemaker is to maintain an adequate
heart rate, either because the heart's
native pacemaker is not fast enough, or there is a block in the heart's
electrical conduction system. Modern pacemakers are externally programmable and allow the
cardiologist to select the optimum pacing modes for individual patients. Some combine a pacemaker and implantable
defibrillator in a single implantable device. Others have multiple electrodes stimulating differing positions within the heart to improve synchronisation of the
lower chambers of the heart.
